You can use front, side, and top views from drawings, sketches, or photographs to help visualize your 3D model in Maya, much like an architect or engineer creates their designs from the plan and elevation views of a blueprint.

You can import 2D images into your orthographic camera views as image planes. An image plane is a 2D object (plane) that places an image file in the scene view. By default, an image plane only appears in the camera to which the image plane is connected. Image planes are also used to create backgrounds and environments when rendering.

When you load an image into an image plane, it appears in your selected orthographic view at the origin along an axis that is perpendicular to the selected orthographic view. You can refer to the image in the orthographic view to define the silhouette and character lines of your model. You can move the image plane, change its transparency, or turn it off.

For this lesson you load two images we’ve provided for the lesson into image planes in the front and side orthographic views of your scene. You’ll refer to them frequently while you model the helmet.

To load reference images into the front and side orthographic views

1. In the Toolbox, click the Four View shortcut from the Layout Shortcuts bar.

   The perspective view is located in the top right corner and the other views show your scene from the top, front, and side.

2. In the front view panel menu, select View > Image Plane > Import Image.
3. Select the image file named HelmetFront.jpg.

   This image can be found in the GettingStarted directory that you set as your Maya project:

   GettingStarted/PolygonModeling/sourceimages

4. In the browser, click the Open button.

   HelmetFront.jpg appears in the front view and depicts a drawing of the helmet.

5. In the side view panel menu, select View > Image Plane > Import Image.
6. Select the image file named HelmetSide.jpg.

   This image can be found in the GettingStarted project directory:

   GettingStarted/PolygonModeling/sourceimages

7. In the browser, click the Open button.

   HelmetSide.jpg appears in the side view.

   NoteThe front and side images for this lesson were created so that the two views are aligned and the height of each image is identical. When you import them as image planes, they appear at the same scale. These are important considerations when you construct your own reference images in the future. Otherwise, your reference images may not align or may be at different scales between the two orthographic views.

   By referring to the image planes in the orthographic views as you work, you can correlate how a feature in one view, appears in another. While a top view reference image is useful in many cases, it isn’t critical for this lesson.

   The image planes can be set so they appear partially transparent to allow you to work with the polygonal components more easily. To do this you’ll select the front and side orthographic cameras and modify the transparency of the images.

To modify the transparency of the reference images

1. In the front view panel menu, select View > Select Camera.

   The camera for the front orthographic view is selected.

2. Display the Channel Box by clicking the Show/Hide Channel Box icon on the Status Line.

   The Channel Box displays the keyable attributes for the Front orthographic camera.

3. In the Inputs section, click the ImagePlane1 name to display the attributes for the image plane.
4. Set the Alpha Gain attribute to a value of 0.25.

   The image appears partially transparent.

5. In the side view panel menu, select the camera and change the Alpha Gain setting for the side view image plane exactly as you changed the front view image plane.

   

   TipYou can change the Alpha Gain at any time if you want the image planes to appear more or less transparent.
6. In the perspective view’s panel menu, select Show > Cameras to temporarily turn off the display of the image planes in the perspective view.
